a combining vowel is used before:
another word root
a prefix
a suffix that begins with a consonant
another word root and a suffix that begins with a consonant
none of the above

Explanation:

In medical terminology, a combining vowel is used between word roots. It is not used before a prefix. When a suffix begins with a vowel, a combining vowel may not be needed; when a suffix begins with a consonant, a combining form (word - root + combining vowel) is often used, but the combining vowel is directly before the word root in the combining form. So it is mainly used before another word root.

Answer:

A. another word root
